摘要: 基于Q460高强角钢两端偏心受压承载力的试验数据,利用ANSYS数值分析对试验数据进行补充,推导出高强角钢单边连接时宽厚比的限值,并在此基础上提出高强角钢单边连接扭转受到约束时杆件承载力计算的实用公式。最后利用相关试验数据验证公式的准确性,对实际中高强角钢单边连接杆件的设计起指导作用。Abstract: According to the experimental data of high-strength angles capacity (Q460) of the unilateral connection and the results of numerical analysis by using ANSYS，the practical formula of the unilateral connection of the ratio of width to thickness for Q460 high-strength angle was derived，and the practical formula of the unilateral connection and restrained torsion of the capacity for high-strength angle was derived also． At the same time，using the related experimental data to validate the exactitude of these practical formulas，which provide a guide for the design of unilateral connection bar of the high-strength angle．
